Operational explanation Oki Data CONFIDENTIAL 2. Operational explanation 2.1 Electrophotographic process mechanism (1) Electrophotographic process The following describes the overview of electrophotographic process. 1. Charging Equally charge the surface of image drum by implying negative voltage to the charged roller due to negative charge. 2. Exposure The light from LED Head is exposed on the negative-charged surface of image drum. The surface electrical potential of the exposed part of image drum surface becomes lower. Then forms electrostatic latent image. 3. Development Negative-charged toner is attracted to the electrostatic latent image due to electrostatic while touching the image drum. Then forms viewable image. 4. Transfer Overlap paper on the surface of OPC drum, from the backside of paper transfer toner image to the paper by applying electrical charge by transfer roller. 5. Fusing The toner image that is transferred to paper is fused on paper by heat and pressure. 6. Drum cleaning The cleaning blade scrapes off the toner that was not transferred and remains on the image drum. 7. Static elimination Residual potential on the image drum is removed. 44556001TH Rev.1 16 / 2. Operational explanation Oki Data CONFIDENTIAL 1. Charging Charge the image drum surface by implying voltage to the charged roller that contacts the image drum surface. Charged roller Power Image drum 2. Exposure The light emitting from the LED Head will be exposed to the negative charged image drum. When the surface electric potential of exposed part of the image drum goes to decrease, the electrostatic latent image complying with image signal is formed. Image drum is coated by basic layer (UL), charge generating layer (CGL), charge transferring layer (CTL) on the basic material aluminum. The thickness of the organic light sensor (OPC) that is consisted by CTL and CGL is approximate 20µm. LED head LED head Power Charged roller Image drum 44556001TH Rev.1 Paper Image drum 17 / 2. Operational explanation Oki Data CONFIDENTIAL 3. Image development Toner is attracted to the electrostatic latent image on the image drum surface, then the electrostatic latent image changes to toner image. 1 As the roller on the supply spot of toner rotates while scrubbing the image-developing roller, fiction electricity occurs between the image developing roller and toner; toner is attracted to the image-developing roller. Image developing plate Charged roller Image developing roller Toner supply roller Image drum 2. The toner that has been attracted to the image-developing roller is dropped down to the developing plate to make a thin toner film on the image developing roller side. 3 The toner is attracted by the exposed part (Low electrical potential part) of the image drum when the image drum contact the image developing roller, so as to see the electrostatic latent image. 44556001TH Rev.1 18 / 2. Operational explanation Oki Data CONFIDENTIAL Note! The necessary bypass voltage in image processing is impressed on the toner feeding roller and image developing roller as show below. While the cover is closed it will be connected and bias will be applied. Toner feeding roller Image developing roller Basic material Image drum 44556001TH Rev.1 19 / 2. Operational explanation Oki Data CONFIDENTIAL 4. Transfer The transfer roller, which is from conductive sponge material, is created to meet intimate attachment of image drum roller surface and feeding paper. The feeding paper is set up on the surface of image drum. Plus charge, which is the converse polarity with toner polarity, is applied from the backside of the paper. As high plus voltage is applied to transfer roller from the power supply, the plus charge on the transfer roller surface is induced and transferred to the paper while the paper contact the transfer roller. The negative charged toner, which has been attracted to the image drum surface, is transferred to the surface of feeding paper by the plus charge of the backside of the paper. Image drum Paper Transfer roller Power 5. Fusing After the termination of transfer the unsettled toner image is settled to paper by heat and pressure while passing between Heat roller and Back up roller. Heat roller is Teflon coated and is mounted by heater that can generate heat (Halogen lamp). The thermistor that contacts the Heat roller adjusts the Heat roller temperature to the temperature specified by the menu complying with the paper width. For safety the thermostat shuts off the voltage supply to the Heater by opening the thermostat in the case of abnormally temperature increasing. The back up roller is held by the pressure springs on each terminal due to the pressure applied.

Drum cleaning After completion of transfer, the toner remaining on the image drum is scraped off by the cleaning blade. As a result of this, the surface of the image drum is cleaned, and the remaining toner that has been scraped off is collected as waste toner in a waste toner area.

Operational explanation Oki Data CONFIDENTIAL 2.2 Printing process The paper fed from Tray 1 and Tray 2 is conveyed by feeding roller, conveying roller, and resist roller. When feeding paper is from MPT, it is conveyed by MPT, feeding roller, and resist roller. After that the feeding paper that is conveyed by image drum and the nip part of transfer roller forms toner image on the paper through electrophotographic process. And then, the toner on the paper is fused by the heat and pressure as the fuser unit passing through. The paper that fused the toner image is ejected from the face down stacker of the ejecting roller. To eject printed pages on the face-up stacker, open the face-up stacker. (Duplex printing is not available during face-up ejection.) The above is about the operations at simplex printing, yet the below explains the operations at duplex printing. While duplex printing, paper, which firstly passes the fuser unit after its backside is printed, is conveyed to the inside of the duplex unit, by the reverse rotation of the first and the second ejecting rollers in a certain period of time after the paper rear end passes the fuser unit. The paper is conveyed by the conveying roller of the duplex unit and then arrives the route for paper feeding from a tray. After that, the paper is handled in the same way as paper fed from a tray for simplex printing.

Operational explanation Oki Data CONFIDENTIAL 2.3 Toner entrance detection Toner sensor detection principle Toner low is detected by the toner sensor (reflect sensor) installed in the printer. The light shield plate is installed in the ID, and its rotation is synchronized with mixing of toner. If the light shield plate or toner sensor is dirty with toner or something, or the ID unit and the toner sensor are facing each other at an improper position due to improper setting of the ID unit or any reasons, toner low cannot be detected correctly, and a toner sensor error occurs. Toner sensor Light board Toner count principle After the image data is transformed into binary data which can be printed by the printer, the data is counted as print dot number by LSI. The amount of the used toner is calculated from this count value, and the residual amount is displayed on the menu. Toner LOW detection (residual amount display on LCD) by the toner sensor is to detect a certain amount of the reduction of the toner left in ID. 44556001TH Rev.1 26 / 3.

Disassembling procedure relating to reassembling is conducted conversely. 3.1 Preparation for parts replacement (1) Be sure to unplug the AC cord and interface cable before starting to replace parts. (a) Unplugging the AC cord by the following procedures. i) Shut off the power switch of the printer. (“ ”) ii) Unplug the AC insert plug of AC cord from the AC socket. iii) Unplug the AC cord and interface cable from printer. Warning Risk of Electric Shock There is a risk of electric shock during replacement of the low voltage power supply. Use insulating gloves or avoid direct contact with any conducting part of the power supply, and caution should be exercised during replacement. The capacitor may take one minute to complete discharge after the AC cord is unplugged. Also, there is a possibility that the capacitor doesn’t discharge because of a breakage of the PCB, etc., so remember the possibility of electric shock to avoid electric shock. (b) Reconnecting the printer by the following procedures. i) Connect the AC cord and interface cable to the printer. ii) Connect the AC insert plug to the AC socket. iii) Turn on the power switch of the printer. (“I”) Shutting off OFF Reconnecting ON (2) Do not disassemble the printer in the case of normal operation. (3) Do not disengage the part that there is not any necessary to touch. Disassembly should be the minimum. (4) Be sure to use the specified maintenance tools. (5) Be sure to temporarily install the small part such as screw, collar, and so on at its original position during disassembling because it is easy to be lost. (6) Do not use the gloves that is easy to occur electrostatic while dealing with IC such as micro-sensor, ROM, RAM, etc. and PCB. (7) Do not put the print circuit board on the equipment or on the floor directly. (8) Do not put the Print Circuit Board on the printer of on the floor directly. 44556001TH Rev.1 27 / 3.

Description for Operation of Second Tray unit Second Tray unit receives a signal from the printer main body and feeds paper to the printer main body. Paper Feed from the Second Tray unit (Tray2) 1. When a signal is received from the printer main body, the pulse motor is rotated (Counterclockwise rotation), and by setting the paper feed clutch to ON, the paper feed roller and pick-up roller are rotated. Therefore, paper in a tray is fed. 2. After hitting the entrance sensor lever and switching the sensor to ON, the paper runs into the conveying roller (Tray 2) that is at rest, and then it is conveyed further by a certain amount. (This action corrects the paper skew.) 3. By setting the regist clutch to ON, the paper is carried by the regist roller.
